Tracked branch details

[dahlbyk]

Proposal to add the following to Branch:

• bool IsTracking { get; }
• Branch TrackedBranch { get; }
• int AheadBy { get; }
• int BehindBy { get; }

Which would satisfy the following:

Branch branch = repo.Branches["test"];
branch.IsTracking.ShouldBeFalse();
branch.TrackedBranch.ShouldBeNull();
branch.AheadBy.ShouldEqual(0);
branch.BehindBy.ShouldEqual(0);

Branch master = repo.Branches["master"];
master.IsTracking.ShouldBeTrue();
master.TrackedBranch.ShouldEqual(repo.Branches["refs/remotes/origin/master"]);
master.AheadBy.ShouldEqual(1);
master.BehindBy.ShouldEqual(2);

(assuming master has one commit origin/master doesn't and origin/master has two commits master doesn't)

I added a feature request to libgit2 to assist in resolving the remote tracking branch reference. For now I'm planning to just hard-code the mapping from refs/heads/<branch> to refs/remotes/<remote>/<branch>.

Makes sense. In fact, it's more or less a standard practice (see this comment). Please, make sure to mark the temporary code with a TODO comment.

Extracted a method where native git_branch_tracked_reference() would be used.

Also added a small convenience overload on Configuration.Get() to get rid of the ugly string concatenation - take it or leave it.

Very nice contrib. Thanks a lot! Now you can reply to your own tweet pointing out to this awesome code :D

Took it. This might require some tweaking later to make it CLS compliant and accept a default value.

Released as part of LibGit2Sharp v0.6.0 :)
